The charger is mainly used for charging power batteries on the electric automobile, and can be classified into a vehicle-mounted type (along with the automobile type) and a fixed type according to whether the charger is mounted on the automobile or not. The fixed charger is generally a large charger fixed in a charging station, and mainly takes high-power and quick charging as main points. The vehicle-mounted charger is arranged in a vehicle, and has the advantages that the vehicle-mounted charger can be charged at any time in any places such as a garage, a roadside or a house where an alternating current power supply supplies power, and the power is relatively low.
At present, most vehicle-mounted chargers charge a power battery in an intelligent working mode, which is directly related to the service life of the power battery and the safety in the charging and discharging process. The most core power battery of the electric automobile is a battery pack formed by packaging a plurality of single batteries, although the current passing through the single batteries is the same, the discharging depths are different, and the deep discharging is a loss to the batteries; and further wear of the battery if the deeply discharged battery is also charged at a conventional current value.
Disclosure of Invention
1. The technical problem to be solved is as follows:
the battery after the deep discharge of the existing vehicle-mounted charger is charged according to the conventional current value, and the battery is further consumed.
2. The technical scheme is as follows:
in order to solve the above problems, the present invention provides a method for charging a storage battery by an onboard charger, comprising the following steps: the first step is as follows: the method comprises the following steps that a charger is initialized, and a central processing unit sends basic information of a storage battery to the charger; the second step is that: the charger receives the basic information of the storage battery, configures basic charging parameters and sends time synchronization information to the central processing unit; the third step: the central processing unit detects the state of a charger, and when the charger is ready, the central processing unit detects the state of a storage battery and starts charging permission information to the charger; the fourth step: the charging machine starts to charge the storage battery, the central processing unit sends charging monitoring data to the charging machine, and the charging machine sends time synchronization information to the central processing unit; the fifth step: monitoring the state of a charger, monitoring the charging process, wherein the charger works normally, the central processing unit judges whether the monitored data meets the charging prohibition condition, when the monitored data meets the prohibition condition, the central processing unit sends charging prohibition information to the charger, the charger stops charging the storage battery after receiving the prohibition information, and the charging process is finished.
In the first step, the battery basic information includes a battery type and a capacity.
The interval of the time synchronization information in the second step and the fourth step is 400-600 ms.
In the fourth step, the charging monitoring data comprises charging voltage, current and temperature data.
In the fifth step, the charge is prohibited under the condition that the storage battery is fully charged or the storage battery is in failure.
3. Has the advantages that:
according to the method for charging the storage battery by the vehicle-mounted charger, the central processing unit monitors and manages the data such as the voltage and the residual capacity of the power battery, when the vehicle-mounted charger is connected with alternating current, electric energy is not immediately output to the battery, the central processing unit firstly collects, analyzes and judges the state of the battery, the charging parameters of the charger are further adjusted, the charging efficiency is improved, the battery is protected, and the service life of the battery is prolonged.
